CONTACT-PLUG FOR ELECTRIC IRONS, HEATING APPLIANCES, AND THE LIKE.

Specification of Letters Patent.

Patented Feb. 2, 1909.

Application filed. August 22, 1907. Serial No. 389,652.

To all whom it may concern:

Be it known that I, RICHARD G. PHEYsEY, a subject of Great Britain,residing at Ontario, county of San Bernardino, and State of California,have invented. a certain new and useful Improvement in Contact-Plugs forElectric Irons, Heating Appliances, and

the Like, of which the following is a specification;

My invention relates to a new and useful improvement in contact plugsfor electric irons and the like, and has for its objectto provide anexceedingly sim le and effective construction of spring clip a apted toengage a binding post or to pass over and contact throughout the entirelength of the tongue and thus avoid confusing of the members.

A further object of-my invention is to entirely inclose the contactmembers so as to prevent them making any contact with the damp materialwhich is being ironed and I thus forming short circuits, and a stillfurther object of my invention is to cheapeir the construction of suchcontact devices by reducing the parts thereof to a minimum, and sodesign the same that they may be made from sheet material by automaticmachinery.

With these and other ends in view, this invention consists in thedetails of construction and combination of elements hereinafter setforth and then specifically designated by the claims.

In order that those skilled-in the art to which this inventionappcrtains may understand how to make and use the same, I will describeits construction in detail, referring by letter to the accompanyingdrawing forming a part of this specification, in which Figure is anelevation of a portion of an electric iron showing my improved contactplug attached thereto. Fig. 2, a top View of the plug. Fig. 3, a bottomview thereof. Fig. 4, a side elevation, a portion thereof being brokenaway to show the recesses therein. Fig. 5, an enlarged view of one ofthe spring clips in contact with its tongue. Fig. 6, a top view of thespring clip. Fig. 7, an edge view of one of the'spri ng clips adapted toengage a binding post.

In carrying out my invention as here embodied, A represents the plug,which is made of any suitable insulating material preferably porcelain,having molded therein the re= ces's'es B and B, with which the squarehole's C and C- connect, said holes being flared at their upper ends asshown in dotted lines'in Fig. 4. Upon one side of this plug at thebottom thereof are formed the slots or channels Band D, which lead intothe recesses B and B respectively.

E represents one of the s ring clips, which consists of one or two memers stamped and bent from sheet metal and riveted together so as to formsprings between the lower or, trons thereof, While the u pe'r portions wich come n contact with eac 1 other form a hole or socket F, in which issecured one of the contact wires leading from the usual twisted cord.One of these spring clips is secured b means of a screw G in one of theholes C an C, so that the lower portion of these clips will extend intothe recesses B and B without touching the walls thereof and in alinementwith the slots D and D.

H represents one-of the contact tongues, which is secured in anyconvenient manner to the terminals H of the heating coils within theiron, here not shown, and the spring cli s are adapted to ass over andembrace t ese tongues or bin ing posts contacting with them throughoutnearly their entire length, thus greatly facilitating the passage of theelectric current-through these contacts and avoiding the liability( ofsparking or fusing at such points.

n practice, a suitable socket on collar I projects'froin the rear ortion of the iron J and the circuit is ma e v.btetweenJthe line wires andthe heating coils Within the iron by simply sliding the plug A throughthin socket.

or collar, which wili guid itinto place over the tongues H, causing t espring members of the clips to embrace said tongues or binding osts, asbefore described. From this it will be seen allof the contact parts andthose which would likewise be liable to divert the direction of thecurrent are entirely by especially ad'apting them for use on round Ibinding posts. I

It will be obvious that these devices are exceedingly simple and cheapof construction and have very little tendency to wear or becomedisarranged.

Having thus fully described my invention, what I claim asnew and useful,is-

1. In combination, an insulating plug having recesses and holes formedtherein and also slots leading from said recesses, two s ring clips eachformed of two members of s iet metal secured together so as to incloseone end of the lead wires, said clips being secured within the holesformed in the plu and extending into the recesses therein, an twotongues or binding posts secured to the terminals of an iron and adaptedto project into the plug and between the spring membersof each of theclips, as specified.

2. In a device of the character described, a suitable plug, two clipseach formed of two pieces of sheet metal secure d together in suchmanner as to provide sockets for the reception of the ends of the leadwires and spring RICHARD G. PHEYSEY.
